DALLAS (April 30, 2019) – Dallas County Health and Human Services (DCHHS) laboratory confirmed mosquito samples have tested positive for West Nile virus.  These are the first positive samples to be confirmed this year.  The mosquito traps were collected from the 75080 zip code of Richardson.

“Mosquito season is here and we want the residents of Dallas County to know to expect more positive traps this season and to therefore remember the 4 Ds.” said Dr. Philip Huang, DCHHS Director.

Residents should use the 4Ds to reduce exposure to mosquitoes:

  • DEET All day, Every day: Whenever outside, use insect repellents that have the active ingredient DEET or other EPA-registered repellents and always follow label instructions.
  • Dress: Wear long, loose, and light-colored clothing outside.
  • Drain: Drain or treat all standing water in and around your home or workplace where mosquitoes could lay eggs.
  • All Day long: Limit your time outdoors all day long as mosquitoes will bite anytime of the day.

Standing water can be treated with EPA-registered larvicides that are available for retail purchase.  Larvicides are products used to kill immature mosquitoes before they become adults.  Larvicides are applied directly to water sources that hold mosquito eggs, larvae or pupae.  When used consistently, larvicides can help reduce the overall mosquito burden by limiting the number of mosquitoes that are produced, according to the Centers for Disease Control and Prevention (CDC).
